It has similar capabilities as IRC – 1C in terms of spatial resolution, spectral bands, stereoscopic imaging, wide field coverage and revisit capability. The improvements carried out in the IRS – 1D satellite taking into account the
IRS – 1C experiences have resulted in better quality imageries.

Mission completed during January 2010 after serving for 12 years and 3 months.
